About the Airtac MG Stainless Steel Mini Air Cylinder MG20X200S
With a 20 mm bore and a 200 mm stroke, this MG series cylinder delivers about 157 N of push and 131.9 N of pull at 0.5 MPa, rising to 219.8 N at 0.7 MPa. It is a double acting JIS round-body mini cylinder built on a SUS304 stainless barrel with a hard-chrome plated rod, so it shrugs off mild corrosion and washdown far better than painted-steel minis in damp or outdoor spots. The covers are riveted onto the barrel for a compact, sealed body, and fixed anti-impact bumper pads soften the stroke ends.
Because the S code is in the model, a magnet is built into the piston, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke detection without any rework. For sizing, plan on roughly 94 N of usable work at 0.5 MPa, which means this cylinder lifts about 8 kg vertically with a 2:1 margin. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG20X200S Is Used
Sensor-checked parts ejector
The built-in magnet and 200 mm reach suit a small pusher on a packaging line where CMSG switches confirm the eject stroke before the next carton indexes.
Light divert gate on conveyors
About 94 N of usable push at 0.5 MPa is enough to swing a lightweight diverter or reject flap on a food-grade conveyor, where the stainless barrel handles frequent washdown.
Lab sample lift
Lifting roughly 8 kg vertically with margin makes this a fit for raising small sample trays or test fixtures in compact laboratory and inspection equipment.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG20X200S the Right Cylinder?
At 20 mm bore this is the smallest MG, pushing 157 N at 0.5 MPa; step up to the 25 mm bore (245 N) if your part weight or friction load creeps above about 90 N, or drop to single-acting MSG/MTG if you only need a spring return. Stroke 200 mm sits well inside the 500 mm standard range, so no made-to-order barrel is needed. Note that with air off or the valve centred the rod drifts freely - for a held position add an external rod lock or a pilot check valve. Order LB foot, FA flange or CB clevis mounting to suit the machine frame, and keep side loads off the 8 mm rod on this longer stroke to avoid bending.
Quick checklist

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MG Stainless Steel Mini Air Cylinder MG20X200S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa that rises to 219.8 N push and 184.7 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed ranges from 30-800 mm/s.
Yes. The S in the model code means a piston magnet is already fitted, so AirTAC CMSG, DMSG or EMSG reed/electronic switches clip directly onto the SUS304 barrel for end-of-stroke signalling. A plain MG without the S suffix has no magnet and cannot take these switches.
